How can I get Apache gzip compression to work

Question

I can t get my site to use gzip compression   I recently watched this video by Chris Coyier over at css-tricks com  In the video  he talks about enabling gzip compression to make websites run faster    As per his instruction  I linked through to github via html5boilerplate com  copied the gzip compression code from their  htaccess file  pasted it into my own  and uploaded it to my site   I ve tested it via gzipwtf com and it doesn t seem to work  Can anyone help me with this   My  htaccess file looks like this     ----------------------------------------------------------------------   Trim www   ----------------------------------------------------------------------  RewriteEngine On RewriteCond   HTTP HOST    orbitprint com   NC  RewriteRule        http   orbitprint com  1  L R 301     ----------------------------------------------------------------------   Gzip compression   ----------------------------------------------------------------------   lt IfModule mod deflate c gt       Force deflate for mangled headers developer yahoo com blogs ydn posts 2010 12 pushing-beyond-gzipping     lt IfModule mod setenvif c gt       lt IfModule mod headers c gt        SetEnvIfNoCase   Accept-EncodXng X-cept-Encoding X 15    15  - 15       gzip deflate  s    s     X -  4 13   HAVE Accept-Encoding       RequestHeader append Accept-Encoding  gzip deflate  env HAVE Accept-Encoding      lt  IfModule gt     lt  IfModule gt       Compress all output labeled with one of the following MIME-types    lt IfModule mod filter c gt      AddOutputFilterByType DEFLATE application atom xml                                     application javascript                                     application json                                     application rss xml                                     application vnd ms-fontobject                                     application x-font-ttf                                     application xhtml xml                                     application xml                                     font opentype                                     image svg xml                                     image x-icon                                     text css                                     text html                                     text plain                                     text x-component                                     text xml    lt  IfModule gt    lt  IfModule gt

If your Web Host is through C Panel Enable G ZIP Compression on Apache C Panel

Go to CPanel and check for software tab.

Previously Optimize website used to work but now a new option is available i.e "MultiPHP INI Editor".

Select the domain name you want to compress.

Scroll down to bottom until you find zip output compression and enable it.

Now check again for the G ZIP Compression.

You can follow the video tutorial also. https://www.youtube.com/watch?v=o0UDmcpGlZI

Your  htaccess should run just fine  it depends on four different Apache modules  one per each  lt IfModule gt  directive   I guess one of the following    your Apache server doesn t have either mod filter  mod deflate  mod headers and or mod setenvif modules installed and running  If you can access the server config  please check  etc apache2 httpd conf  and the related Apache config files   otherwise  you can see which modules are loaded via phpinfo    under the apache2handler section  see attached image    EDIT  OR  you can open a terminal window and issue the command sudo apachectl -M that will list the loaded modules  if you get an http 500 internal server error  your server may not be allowed to use  htaccess files  you are trying to load a PHP file that sends its own headers  overwriting Apache sheaders   thus  confusing  the browser    In any case  you should double-check your server config and error logs to see what s going wrong  Just to be sure  try to use the fastest way suggested here in Apache docs   AddOutputFilterByType DEFLATE text html text plain text xml   and then try to load a large textfile  preferably  clean your cache first     EDIT  If the needed modules are there  in the Apache modules dir  but aren t loaded  just edit  etc apache2 httpd conf and add a LoadModule directive for each one of them   If the needed modules aren t there  neither loaded  nor in the Apache modules directory   I fear that the only option is reinstalling Apache  a complete version

Ran into this problem using the same  htaccess configuration  I realized that my server was serving javascript files as text javascript instead of application javascript  Once I added text javascript to the AddOutputFilterByType declaration  gzip started working   As to why javascript was being served as text javascript  there was an AddType  text javascript  js declaration at the top of my root  htaccess file  After removing it  it had been added in error   javascript starting serving as application javascript

Enable compression via  htaccess  For most people reading this  compression is enabled by adding some code to a file called  htaccess on their web host server  This means going to the file manager  or wherever you go to add or upload files  on your webhost   The  htaccess file controls many important things for your site   The code below should be added to your  htaccess file      lt ifModule mod gzip c gt  mod gzip on Yes mod gzip dechunk Yes mod gzip item include file   html  txt css js php pl   mod gzip item include handler  cgi-script  mod gzip item include mime  text    mod gzip item include mime  application x-javascript   mod gzip item exclude mime  image    mod gzip item exclude rspheader  Content-Encoding   gzip    lt  ifModule gt    Save the  htaccess file and then refresh your webpage   Check to see if your compression is working using the Gzip compression tool

First of all go to apache bin conf httpd conf and make sure that mod deflate so is enabled   Then go to the  htaccess file and add this line      SetOutputFilter DEFLATE   This should output all the content served as gzipped  i have tried it and it works

In my case append only this line worked  SetOutputFilter DEFLATE

It is better to implement it as in the snippet below   Just paste the content below in your  htaccess file  then  check the performance using  Google PageSpeed  Pingdom Tools and GTmetrics     Enable GZIP  lt ifmodule mod deflate c gt  AddOutputFilterByType DEFLATE text text text html text plain text xml text css application x-javascript application javascript BrowserMatch  Mozilla 4 gzip-only-text html BrowserMatch  Mozilla 4  0 678  no-gzip BrowserMatch  bMSIE  no-gzip  gzip-only-text html  lt  ifmodule gt     Expires Headers - 2678400s   31 days  lt ifmodule mod expires c gt    ExpiresActive On   ExpiresDefault  access plus 1 seconds    ExpiresByType text html  access plus 7200 seconds    ExpiresByType image gif  access plus 2678400 seconds    ExpiresByType image jpeg  access plus 2678400 seconds    ExpiresByType image png  access plus 2678400 seconds    ExpiresByType text css  access plus 518400 seconds    ExpiresByType text javascript  access plus 2678400 seconds    ExpiresByType application x-javascript  access plus 2678400 seconds   lt  ifmodule gt     Cache Headers  lt ifmodule mod headers c gt      Cache specified files for 31 days    lt filesmatch     ico flv jpg jpeg png gif css swf    gt    Header set Cache-Control  max-age 2678400  public     lt  filesmatch gt      Cache HTML files for a couple hours    lt filesmatch     html htm    gt    Header set Cache-Control  max-age 7200  private  must-revalidate     lt  filesmatch gt      Cache PDFs for a day    lt filesmatch     pdf    gt    Header set Cache-Control  max-age 86400  public     lt  filesmatch gt      Cache Javascripts for 31 days    lt filesmatch     js    gt    Header set Cache-Control  max-age 2678400  private     lt  filesmatch gt   lt  ifmodule gt
